I hav a 1999 ram 1500 w/a 5.9l. I need 2 kno the proper pcm installation procedure.

 

Unbolt old one
Unplug old one
Reverse the order

Turn key forward wait 15 seconds before starting the vehicle

 

Well, see, thts wat i'd think 2. But my old pcm got fried wen i disconnected the negative cable then reconnected it. Wen th cable was very near touchin the negative battery terminal, it sparked/arced & totally shut down. The only thing tht'll happen wen i turned th key on is th odometer will blink.

So, i'm kinda wary bout jst pluggin th new pcm strate in bcoz i'm scared as hell of fryin it again :/

 

Disconnect the battery, and make sure the ignition is off when you hook it back up. That process should NOT fry the PCM.

 

Any1 else plz????

 

What HeyYou said. There really isn't anything special procedure when changing the pcm. Battery disconnected and key off.
But, if you fry pcm just by plugging it, I suspect there has to be a short somewhere.

 

No, it didnt fry by pluggin th pcm in. It sparked/arced & fried wen goin 2 reconnect th negative battery cable. Frm wat all i read up on this, its a prob with rams frm like 97-02.

 

If HeyYou says something, you can bet it's correct. I doubt you'll find better advice, or many who will disagree with him.

 

If you are getting a heavy spark when you hook the battery back up, there is a draw somewhere, that shouldn't be there. Does the battery go dead overnight? Is your charging system working properly?

 

Hey, thanx all!!! I got th new pcm in and secured/plugged in, hooked th battery up & it fired right up!!!

Ok, a new issue.....its doin wat told me th pcm was th issue in th 1st place. It fired right up, but th odometer is still blinkin & all th gauge needles r jumpin now (they werent b4

I 4GOT BOUT TURNIN TH KEY ON & WAITIN ugh :/
